The automatic speaker verification spoofing and countermeasures (ASVspoof) challenge series is a community-led initiative which aims to promote the consideration of spoofing and the development of countermeasures. ASVspoof 2021 is the 4th in a series of bi-annual, competitive challenges where the goal is to develop countermeasures capable of discriminating between bona fide and spoofed or deepfake speech. This document provides a technical description of the ASVspoof 2021 challenge, including details of training, development and evaluation data, metrics, baselines, evaluation rules, submission procedures and the schedule.

  1. SONAR: Spectral-Contrastive Audio Residuals for Generalizable Deepfake Detection

    cs.SD 2025-11 conditional novelty 6.0 of 10

    SONAR improves audio deepfake detection by explicitly aligning low- and high-frequency representations for real speech and repelling them for fakes, setting new benchmark EERs on ASVspoof 2021 and in-the-wild data.

  2. RoVo: Robust Voice Protection Against Unauthorized Speech Synthesis with Embedding-Level Perturbations

    cs.LG 2025-05 conditional novelty 6.0 of 10

    RoVo perturbs BARK codec embeddings instead of raw audio, and reports that speech-synthesis clones of protected voices are rejected by speaker verification 70+ percentage points more often, with better robustness to s...
